I think of Sorrel as a girl's name.

I like Heath and Oakley as previously suggested! I also like Rowan from your list a very nice name!
I actually like the name Orion too (like the star constellation, but maybe that's going down a different theme)

Please don't call him Ember, Ember is too close to Amber and people would definitely get confused. It is very feminine too
